Research Interests

Despite many therapeutic successes, cancer remains a major cause of mortality in the US. Natural products (NPs) represent the best source and inspiration for the discovery of drugs and molecular targets. Our aim is to discover effective and non-toxic NP-based anticancer drugs. Working with NCI we have recently discovered a class of plant-derived NPs useful in cancer immunotherapy. The main focus of our current research is to utilize medicinal chemistry approach to obtain their analogues for preclinical evaluation.
Leslie Gunatilaka is Professor at the School of Natural Resources and the Environment and Director of the Natural Products Center. He is also Adjunct Professor of Department of Nutritional Sciences, and a member of the Arizona Cancer Center. He is a member of several professional societies, editorial boards, and pharmaceutical company advisory groups. He is a Fellow of the Academy of Sciences for the Developing World (TWAS), Italy, and the National Academy of Sciences, Sri Lanka. Dr. Gunatilaka has over 200 peer-reviewed publications and book chapters and over 150 communications in natural product science to his credit. He is the recipient of the Sri Lankan Presidents’ gold medal for “creating a center of excellence in natural products research at the University of Peradeniya, Sri Lanka” (1987), CaPCURE award for “dedication to ending prostate cancer as a risk for all men and their families” (2000), Research Faculty of the Year Award of the UA College of Agriculture and Life Sciences (2003), the UA Asian American Faculty, Staff and Alumni Association Outstanding Faculty Award (2005), and the UA Leading Edge Researcher Award for Innovative Research (2012). He has delivered over 100 invited lectures worldwide and was the Chief Guest and Plenary Lecturer at the International Herbal Medicine Conference held in Sri Lanka (2005), and the Keynote Speaker and the Guest of Honor at Chemtech-2007, an International Conference organized by the Institute of Chemistry, Ceylon. His current research interests include discovery, identification of protein targets, and structure-activity relationship (SAR) studies of natural product-based drugs to treat cancer, neurodegenerative, and other diseases from plants, and plant- and lichen-associated microorganisms, maximization of chemistry diversity and production of microbial and plant secondary metabolites, and scientific investigation of medicinal plants and herbal supplements.
